And, this issue seems "fixed" in 5.11-rc7 so I think the kernel dev
may have
some idea of it.

Looks like

fixes it (at least with Ken's configuration). I've applied this patch
to 5.10.13 tree (I had also to download the skl_dmc_ver1_27.bin
firmware to /lib/frimware/i915 to allow the build with Ken's config).

Pierre, thanks for finding the patch.  After I'd gone to bed it
occurred to me that I would need to download earlier 5.11-rc kernels
to find which one fixed it, and then do a reverse bisect to find
which commit fixed it (the logic of that always makes me even more
confused than normal), so many thanks for saving me that confusion!

I've now applied that to 5.10.15-rc1 and confirmed it builds and
boots.  Gotta go out right now for provisions, will use my other
mail to inform the relevant people that this fixes builds with
binutils-2.36.1 when I get back.

The 5.10.15 kernel is now out, but I can confirm that the patch above has NOT been incorporated.

Do we know when 5.11 will be released? We are scheduled to go into package freeze on Sunday, but if it is not fixed yet, I think we should wait for it.
